Question

我的网站有一个基本的default.vcl，它正在运行。

我添加了下面的代码来检测并为用户提供不同的主题，如果来自PC或手机。添加以下代码以检测移动设备后，清漆无法启动。

如何解决此问题，以便清漆检测到移动设备，因此如果从移动设备访问移动主题，则可以在同一网址中提供移动主题

    * First, set up a backend to answer the request if there's not a cache hit.

您可以尝试使用

启动清漆

varnishd -F -f /etc/varnish/default.vcl

这样您就可以看到所有消息/错误。顺便说一下：你加了devicedetect.vcl。没有这个文件，很难说出现了什么问题;）

在varnish {default.vcl}中添加移动检测后，varnish无法启动
